BOTTLE-CLOSURE.

Specification of Letters Patent.

Application filed September 22, 1906. Serial No. 335,787.

.' its objects to produce" a comparatively simple, inexpensive device of this character which may be conveniently applied for use, one whereby the bottle'will be effectually sealed, and one which may be readily removed in the operation ofopening the bottle.-

With these and other objects in view, the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanying drawings: Figure 1 is an elevation of a portion of a bottle equipped with a closure embodying the invention. Fig. 2 is a vertical, longitudinal section taken centrally through the bottle neck. Fig. 3 is a plan view of the cap in blank. Fig. 4 is a detail, sectional view taken centrally through the cap and showing the same prior to bending the flanges to engaging position.

Referring to the drawings, l'des'ignates a bottle neck having a flange or head 2, there being applied to the mouth of the bottle a metal cap or closure 3 in which is arranged and secured a cork or other sealing disk 4.

The closure 3, is, in accordance with my invention, composed of a single blank of sheet metal, said blank, as seen in Fig. 3, being of circular form and having a series of radial,

substantially V-shaped recesses or incisions 5, each opened outwardly at the marginal edge of the blank and forming on the closure a series of radial lips or projections 6, there being preferably an equal number of the recesses 5, thereby producing an even number of lips 6. After forming the blank which may be-accomplished by stamping the material, said blank is bent into the initial shape seen in Fig. 1, with the lips 6 semi-circularly grooved and inclined upwardly and outwardly, as shown, after which the disk 4 is fixed in the cap by means of shellac or other suitable adhesive.

In practice, the cap having the sealing disk 4 fixed therein is positioned on the mouth of the bottle and the lips or flanges 6 Patented May 14, 1907.

bent downward, as seen in Fig. 2, thereby i carryin the material of the cap inward beneath the head 2 to thus fix the cap securely in place on the bottle neck, it being observed that in bending the lips the spaces 5 allow for the proper displacement of the metal to insure proper disposition of the flanges in engaging the head 2.

It is to be understood that the form of the neck of the container may be varied as desired without defeating the invention and the cap in its initial completed condition is of such size that it must be snapped under pressure over the flange 2 prior to sending the lips or flanges 6 downward for effecting se cure engagement of the cap with the bottle neck.

Having thus described my invention, what I claim is: I

A bottle closure formed from a single blank of bendable material having a series of radial incisions producing lips or flanges designed to be bent into engagement with a bead formed at the mouth of the bottle, said closure being made in the form of a cap and the flanges be ing curved inwardly at an intermediate point to produce an engaging portion of restricted diameter to be snapped under pressure over the bead, the incisions being of substantially V-shape to allow for displacement of the material in the formation of the cap.

In testimony whereof, I aflix my signature in presence of two witnesses.
